Network

Results by Type

Enter a hostname to query its A, AAAA, MX, TXT, and CNAME records.

A domain resolving correctly over legacy IPv4 says nothing about whether it also resolves over IPv6, and checking that specifically means looking up an AAAA record, a detail that's easy to overlook entirely if a lookup tool only ever checks the older record types most domains have carried for decades. This tool queries A, AAAA, MX, TXT, and CNAME records for any domain, including IPv6 addressing alongside the more traditional record types.

Useful for confirming a domain actually resolves correctly over IPv6, not just legacy IPv4, checking whether a newly added AAAA record has propagated, or auditing a domain's records with modern IPv6 addressing included rather than assumed.

Quick answers for DNS Lookup

Where do the DNS results come from?
Live queries to Google's public DNS-over-HTTPS resolver (dns.google), not cached or simulated data.
Can I look up multiple record types in one click?
Yes, toggle any combination of A, AAAA, MX, TXT, and CNAME and Lookup All queries them simultaneously.
What happens if a record type does not exist for the domain?
That type's card shows "No records found" rather than an error, while a genuine lookup failure shows "Lookup failed" instead.
